UNITED STATES PATENT OFFICE.

CHARLES H. NOWACK, OF OAK PARK, ILLINOIS, ASSIGNOR TO AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW- JERSEY.

GREASE-GUN.

Application filed December To all whom it may concern:

Be it known that I, CHARLES H. NOWACK, a subject of the Emperor of AustriaHungary, residing in Oak Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Grease- Guns, of which the following is a specification.

This invention relates to dispensing packages, and has more particular reference to packages provided for the marketing of heavy greases and the like of the type commonly termed grease guns, wherein the grease is adapted to be forced as occasion requires, from the package out through an opening or nozzle in desired quantities for use.

A principal object of this invention is the provision of a package of the character described from which heavy grease may be forced, as occasion may require, through the exercise of little effort and without the use of auxiliary tools or implements.

A form of package embodying my present invention is particularly adapted for the containing of grease for automobile users and the like Where it is desirable that the'package occup little room and be ready for instant use. uch a package, to be successful, must be capable of ready manipulation and this independently of the condition of the grease at its time of use. In cold weather grease hardens appreciably and the means provided to eject it should be capable of ejecting it in this condition. y

. A still furtherobject of the invention is the provision of a package of this kind which will protect the unused material from accumulation of foreign matter such as dust and grit likely to damage the parts to be lubricated. v

,A further object of the invention is the provision having been. once" emptied cannot again be used for the containing. of like material.

A still further object of the invention is the provision of such a package from \which the material, will becompletely ejected.

. A-still further object of the invention is which,;whe n packedfifor shipment, will occupy a minimum space having practically noprojecting parts to interfere with stacking or box1ng,and. which might be damaged in shipment', such parts as extend out- Specification of Letters Patent.

of such a package which, after.

is, 1915. Serial No. 67,491.

wardly from the package when in use, being conveniently packed separately and readily assembled by the retail dealer or user.

An additional object of the invention is the provision of such a package, the parts of which may be readily assembled and the package filled.

A still further object of the invention is the provision of a package of this character in which a removable key is used to'ej ect the material so that the user can, if he desires, prevent surreptitious manipulation of the package by removal of the key.

Other objects and, advantages of the invention will be apparent as it is better understood from the following description when considered in connection with the accompanying drawing illustrating a preferred embodiment thereof. I

On the drawing,

Figure 1 is a, perspective view, of a grease gun embodying my invention;

Fig. 2 is a longitudinal section of the same;

Fig. 3 is a transverse section taken substantially on the line 3--3 of Fig. 2;

Fig. 4 is an enlarged partial view show ing certain details of construction;

Fig. 5 is a view similar toFig. 1 of a grease gun also embodying my'present invention and somewhat diflt'erently constructed;

Fig. 6 is .a longitudinal section taken through the gun shown in Fig. 5;

7 is a transverse'section of the same;

Flg. 8 is a perspective view of the ejecting1 strip used in the gun shown in Fig. 5; an

Fig. 9 is a similar view of theguard.

The'grease gun shown in Figs. 1 and 4 and embodying my invention consists primarily of' a flat elongated body generally designated at A, having at one end a dispensing nozzle B, and carrying within it an ejecting strip C;

g The body. A is of rigid, metallicconstruction and consists of sidewalls 7 and 8 seamed at their edges to a strip 9 forming the-top, bottom and end walls, the vertical edges being somewhat rounded, for a purpose to later appear. Theends of the strip-Q are secured'together by interen aging books 10 atone corner of the body. or convenience of descriptlon, the end 11 adj accntthis corner, will be termed-the front end of the body, and the end 12, remote from it, the rear end. The front end 11 is provided with -a dispensing opening 13 surrounded by a' this end the strip C extends along the bottom wall to substantially the rear end of the body and is looped back upon itself to extend along the inside of the top wall to adjacent the'front end 11 lying well-into the rounded corners of the end 12. At the front the free endis bent to provide a part 17 engageable by a rotatable key or member 18 which is insertible through suitably formed apertures 19 in the side walls 7 and 8. Theapertures 19 form a bearing on the body for the winding shaft of the member 18. This key is split, as indicated at 21, to pass on opposite sides of thepart 17 to permit it to grip the part 17 ,when the key is turned to roll the strip. about the key andreduce the effective space in the package, causing an ejectment of grease or other material. The strip C, when first placed in the body, provides a space within itself equal almost to the capacity of'the body.

A guard 22 formed of a bent sheet having one end 23 extending between the strip and the to front corner is provided to extend aroun the-key enga ed end of the strip C.

and to form a cham er for the strip as 'it rolls. The other edge or end of theog llard strip is bent, asshown at 24 in Fig. 2, in order that when the strip is completely rolled up this end will be pulled around and force the 7 last remaining material to or out through the dispensing opening 13.

Referr ng now more particularl to 5 to 9., which show a slightly di erent embodiment of the invention and what is at present believed to be the preferred embodimentof the invention, reference character D indicates the of the container, reference character Ethe nozzleand reference.

character F the ejecting sheet or strip. The

structure shown in these figures is substant ally hke that shown in Figs. 1 to 4 and alreadydescribed, except in certain particula rs as will now be described. The strip F is wound differently upon the s lit ke 31. It will" y be noted that in Fig.2 t e strip exhind the key and thence around it, f in th winding operation, while in Figs. 5, 6 and 8. it"extends up to adjacent "the keyand then beyond it and around behind it so that as the strip approaches the end of its winding, it lies closer to the nozzle opening 32, thereby greatly aiding the guide 33 in forcing the last bit of grease from the container or ease gun.

In the cons ruction shown in these figures the nozzle 0 ening 32 is centrally disposed instead of being located off-center, as in Fig. 1, although this is a mere matter of preference of construction.

One important difference between the two embodiments resides in the method of securing the relatively stationaryend 34 of the strip tothe body. Instead of being provided with lips resembling the lips 16 and adapted for insertion in the seam between the ends of the body-forming strip .35, this end of the ejecting strip is provided with laterally extending'lugs or lips 36 which are divided from the main part of the strip by score lines 37. Similarly extending lips 38 are provided from the edges of the side of thestrip adapted to lie along the adjacent elongated face 39 of the body-forming strip 35 and these lips are also divided from the body part of the ejecting stri by score lines 41. The lips 36 and 38 are ormed into the.

seam 42 between the sides 43 and the strip 35. .When'theejecting strip is rolled up lips 38 are torn away during a relatively early part ofthe ejectmentsv and later the lips 36 are also torn away as the last/of the grease is forced from the body. These lips servethe dual function of securing the strip in proper position, within the container and also of materially aiding in the assembling of its parts by the manufacturer through provi ding for easy alinement and through guarding against any tendency the strip may have to twist or assumean inoperative position. The guard 33 is also provided withlips44 adapted to be included in the.

seams 42 to positively hold the guard in place. r p In practice, when either of the forms shown is used, the body is completely formed with the strip and guardin place, and the goods then packed in it through insertion throughthe nozzle openin which opening may be closed in any suitable fashion to render the package ready for shipment, the I nozzle and key being preferably furnished as separate parts. -The key is readily insertible to engage upon the end of-the' ejecting strip and the nozzle of course readily replaces the closure used. A small opening 25' (Fig. 1) is preferably formed with a nail or other sharp pointed instrument in the rear end of the body by'the user to facilitate the ejectment" by admitting air behind the strl The nozzle itself may be provided, if desired, wit-h acap 25, friction or otherwise, to be used bythe' consumer to I 1 close the nozzle should he desire to leave the nozzle on'the package between its periods of use. The key may be withdrawn and inserted as desired. and when the strip has been partially rolled to prevent stealing of the grease. The whole device is simple and effective and can be cheaply manufactured.

It is thought that the invention and many of is attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any. of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

l. A dispensing package comprising a relatively long and narrow body having a dispensing opening in one of its ends, a flexible strip looped within said body and extending in substantially straight lines away from opposite sides of said opening and about material carried therein, one end of the strip being attached to the body at one of the forward corners thereof, a winding device mounted to turn within the body in the corner thereof opposite to said attachment, the other end of said strip being attached to said windingdevice, and a nozzle attached to the body around said opening and forming a prolongation of the body in line with the space between the'two sides of the looped strip.

2. A dispensing package comprising a seamed body having a dispensing opening, a strip of flexible material looped within said body and having'a part seamed between parts of the body adjacent said opening at one side thereof and having its end engaged with a rotatable member at the other side of said opening, rotation of said member windingthe strip thereon to produce ejectment of material. said. strip being disengaged from its detachable connection with said body when completely wound on said rotatable member.

A dispensing package comprising a body having a dispensing opening, a flexible strip looped within said body and about material carried thereby, a rotatable member on which said strip may wind to produce ejectment of material, and a guard for said member.

4. A dispensing package comprising a body having a dispensing opening, a flexible strip looped within said body and about material carried thereby, a rotatable member on which said strip may wind to produce ejectment of material, and a guard for said member, said guard bearing against said strip to clean the material therefrom as it winds on said rotatable member.

5. A grease gun having in combination an elongated body rectangular in cross section and formed at one end with an aperture for the expelling of grease, therefrom, and a flexible loop having its ends connected with the body near said aperture, the limbs of the loop being flat and parallel with two of the sides of the body and extending in straight lines substantially from end to end of the body, the connection of one of the ends of the loop having means for winding up the same, said aperture having a collar and nozzle.
